== | == 0x18000 - DM (Dispatcher Manager) == | ||
*Dispatcher Manager runs in Process 3. | |||
*When SLL (Secure LPAR Loader) creates GamesOS LPAR and loads it, it also creates a VUART with port number '''10''' owned by GameOS using a service provided by Dispatcher Manager (0x18001 - Construct Service Port). | |||
*Dispatcher Manager communicates with GameOS through this VUART. It opens the file '''/proc/partitions/<LPAR id>/vuart/10'''. When the file '''/proc/partitions/<LPAR id>/vuart/10''' is opened by Dispatcher Manager, the Hypervisor creates a peer VUART which is connected to the GameOS's VUART 10. | |||
*After that Dispatcher Manager reads requests from this VUART sent by GameOS and dispatches these requests to services (functions) provided by Hypervisor Processes through sockets. '''Through VUART and Dispatcher Manager, the GameOS LPAR has access to all services provided by Hypervisor Processes.''' | |||
*However, the services provided by Hypervisor Processes are protected by Security Policy Manager (SPM). Before Dispatcher Manager routes the requests from GameOS to these services, it consults SPM (by using 0x11001 service of SPM) and checks if the GameOS has access rights to the requested service. If not then the request is not routed. | |||
*DM overwrites the LAID sent in SS packet header with the LAID of the LPAR that sent the request. So, no matter what LAID you send in SS packet header, it will be always overwritten with the correct one by DM. That is the reason why e.g. USB Dongle Master Key cannot be decrypted by GameOS without patching DM. But with HV access rights, DM can be easily patched and access to SYSCON can be gained. | |||
*Linux LPAR doesn't have a VUART communication link to Dispatcher Manager. | |||
*I tested VUART 10 on GameOS with PSGroove and it's there. | |||
*On GamesOS, '''_ss_multiplexer''' accesses DM (VUART 10) | |||

generate_new_lpar_mem_region_address - 002C6570 (3.41) | |||
*The function returns a new LPAR memory region address. | |||
*This method is used e.g. in all HV calls which create any kind of memory regions, e.g. '''lv1_allocate_memory''', '''lv1_map_htab''', '''lv1_undocumented_function_114''', '''lv1_construct_logical_spe''', '''lv1_map_device_mmio_region''' or '''syscall 0x10040'''. | |||
==== Encoding LPAR Memory Region Start Addresses and Sizes ==== | |||
*Size of LPAR memory region is encoded in the LPAR memory region start address. | |||
*That is why e.g. the LPAR Memory Region Start Addresses of LPAR Memory Region of size 4096 byte begin with '''0x300000000000''', '''0x300000000000 >> 42 = 0xC = log2(4096)'''. | |||
*Each LPAR has a counter (8 bytes) which is incremented by 1 every time a new LPAR Memory Region is created. | |||
*Before incrementing, the counter is shifted left by '''log2(LPAR Memory Region Size)''' and ored with '''log2(LPAR Memory Region Size) << 42'''. | |||
LPAR Memory Region Start Address >> 42 = log2(LPAR Memory Region Size) | |||
LPAR Memory Region Start Address = (log2(LPAR Memory Region Size) << 42) | | |||
(counter << log2(LPAR Memory Region Size)) | |||
===== LPAR Memory Region Address Counter ===== | |||
*LPAR Memory Region Address Counter is stored at address: '''0x38(LPAR ptr) + 0x9E8''' | |||
*LPAR1's Memory Region Address Counter is at address '''0x00677A48''' in HV dump 3.15 | |||
*LPAR2's Memory Region Address Counter is at address '''0x007632D8''' in HV dump 3.15 | |||
*LPAR1's Memory Region Address Counter is at address '''0x00677A48''' in HV dump 3.41 | |||

== | == Direct Map Memory Region class == | ||
This type of memory region is created in HV call '''lv1_undocumented_function_114'''. | |||
'''lv1_undocumented_function_114''' allows you to map any memory address into LPAR's memory address. | |||
* The HV call '''lv1_undocumented_function_115''' destroys a memory region of this type. | |||
* HV allows GameOS to create objects of this type of size 0 only !!! But it can be exploited with a dangling HTAB entry. | |||

=== Exploiting HV with memory glitching and HV call lv1_undocumented_function_114 === | |||
Here is a short description of the method i used to exploit HV from GameOS 3.15 and 3.41. | |||
* First i used the Geohot's method to create a dangling HTAB entry. | |||
* Making memory glitch work on GameOS was the largest of my obstacles but i solved it and i'm able to create a dangling HTAB entry from GameOS within 1-3 minutes. | |||
* Then i created many '''Direct Map Memory Region''' objects of size 0 with HV call '''lv1_undocumented_function_114''' and checked if they are within the page to which the dangling HTAB entry points to. | |||
* When i found one such '''Direct Map Memory Region''' object i patched the size of this object to 0x1000. Then i pointed this memory region object to the code of HV call '''lv1_undocumented_function_114''' and patched 4 bytes in this HV call which allows me to create any '''Direct Map Memory Region''' objects without any restrictions. | |||
* Function '''LPAR_construct_direct_mapping_mem_region''' which is used by HV call '''lv1_undocumented_function_114''' has a parameter (register %r9) and when this parameter is not 0 then HV will allow you to create any '''Direct Map Memory Region''' objects without restrictions, but unfortunately the HV call '''lv1_undocumented_function_114''' passes 0 in this parameter, so i just patched it. | |||
* Then i mapped whole HV memory range with the patched HV call '''lv1_undocumented_function_114''' into the address space of GameOS. | |||
* And now you have read/write access to the whole HV. | |||
* $ONY could fix this exploit by disallowing creating of '''Direct Map Memory Region''' objects of size 0, but i know tons of other HV C++ classes which will allow me to exploit the HV in a similar way, so it wouldn't bring $ONY anything :-) And they have to change member variable offsets in those objects to make sure that i cannot patch them easily :-) | |||

= Event Notification = | |||
*Event Notfication is used e.g. to notify a LPAR about some event, e.g. device interrupt or notify a LPAR about destruction of another LPAR. | |||
*For example Process 9 is notified through Event Notification when LPAR 2 is destructed. | |||
*During LPAR construction, Process 9 creates an Outlet object with '''syscall 0x1001A''' and then passes the outlet ID to the '''syscall 0x10009''' that constructs the LINUX LPAR. In this way Process 9 is notified when LINUX LPAR is destructed. | |||

=== VUART IRQ Bitmap === | |||
*At address 0x38(LPAR ptr) + 0x158 is the VUART IRQ Bitmap owned by HV for LPAR (4 * 8 bytes = 256 bits) | |||
*At address 0x38(LPAR ptr) + 0x150 is stored the physical address of LPAR's VUART IRQ Bitmap that was passed to '''lv1_configure_virtual_uart_irq''' | |||
*When a VUART interrupt is generated by HV then first the VUART IRQ Bitmap owned by HV is updated and then this bitmap is copied to LPAR's VUART IRQ Bitmap, so VUART IRQ Bitmap is stored twice, once in HV and once in LPAR, just like IRQ State Bitmap. | |||
*VUART IRQ Bitmap is not allowed to cross page boundary of LPAR memory region where it is stored. HV checks it and makes sure that it doesn't happen. | |||
*'''GameOS 3.41''' VUART IRQ bitmap is at address '''0x80000000003556E8''' and of size '''32 bytes (256 bits, each bit corresponds to a VUART port)'''. | |||

== | == IRQ State Bitmap == | ||
*There is one IRQ State Bitmap (256 bits = 32 bytes) per thread of Logical PPE | |||
*'''HSPRG0 value is per thread''', so there are 2 HSPRG0 values in HV dump !!! | |||
*The IRQ State Bitmap of a thread is stored at -0x68E0(HSPRG0) | |||
*When an Event or Interrupt happens then the bitmap at 0x68E0(HSPRG0) is updated | |||
*The physical address of '''LPAR's IRQ State Bitmap''' of thread is stored at offset -0x68C0(HSPRG0) | |||
*The address of LPAR's IRQ State Bitmap is passed to Hypervisor through HV call '''lv1_configure_irq_state_bitmap''' | |||
*'''lv1_detect_pending_interrupts''' returns value of current IRQ State Bitmap. | |||
*The IRQ State Bitmap is updated if an Outlet object is assigned to VIRQ and when Outlet generates an event | |||
*After IRQ State Bitmap update, it's copied to LPAR's IRQ State Bitmap and a hardware interrupt is generated so that LPAR can read it's IRQ State Bitmap and handle interrupts. | |||
*So, IRQ State Bitmap is stored twice, once in HV and once in LPAR, just like VUART IRQ Bitmap. | |||
*'''GameOS''' IRQ state bitmap is stored at address '''SPRG0 + 0x1C0 and of size 64 bytes (256 bits state + 256 bits mask) per thread of Cell CPU'''. So there are 2 IRQ state bitmaps. | |||

==Sending Packets== | |||
* Before sending new packet to SYSCON, the Hypervisor checks 2 words at offsets 0x2400008DFF0 and 0x2400008CFF4. | |||
* The Hypervisor busy waits until (value + 1) at offset 0x2400008CFF4 is NOT equal to value at offset 0x2400008DFF0. | |||
* The packet is sent with 4 byte transfers. | |||
* First, the Hypervisor sends the header of the packet, 4 word transfers. | |||
* The header is written beginning at the address 0x2400008D000. | |||
* After that the Hypervisor sends the body of the packet, with 4 byte transfers too. | |||
* The body is written beginning at the address 0x2400008D010. | |||
* If the packet size is NOT divisible by 4 then the Hypervisor sends the remaining bytes (at most 3) as a word padded with 0s. | |||
* After the packet body was written, the Hypervisor calculates checksum of the whole packet and writes it at the address where the last word of packet body was written + 4. | |||
<pre> | <pre> | ||
uint32_t cksum = 0; | |||
for (i = 0; i < packet_size; i++) | |||
cksum -= packet[i]; | |||
cksum = cksum & 0xffff; | |||
</pre> | |||
* After the packet checksum was written, the Hypervisor reads the value at offset 0x2400008DFF0, modifies it and stores back: | |||
<pre> | |||
value = value + 1; | |||
value &= 0xffff; | |||
value = (value << 16) | value; | |||
</pre> | </pre> | ||
* To notify the SYSCON about the new packet, the Hypervisor writes 0x1 to address 0x2400008E100. | |||
== | ==Receiving Packets== | ||
* | * The Hypervisor installs an interrupt handler for the SYSCON. | ||
* | * First, the Hypervisor reads a word from address 0x2400008E000, ors it with 0xFFFFFFFD and writes the value back. | ||
* Then, the Hypervisor reads a word from address 0x2400008E004 and tests if bit 0x2 is set or not. The bit 0x2 should be not 0 or else the Hypervisor panics. | |||
* After that, the Hypervisor reads a word at address 0x2400008CFF0 and 0x2400008DFF4. If there is a new packet pending from SYSCON, then the (value + 1) at 0x2400008CFF0 should be equal the value at 0x2400008DFF4. | |||
* The Hypervisor reads the header of the packet beginning at the address 0x2400008C000. | |||
* The header is read with 4 word transfers by the Hypervisor. | |||
* The byte at offset 1 in the packet header must be 1 or else the Hypervisor discards the packet as invalid. | |||
* The Hypervisor calculates the checksum of the packet header and checks it with the checksum stored in the header. If they don't match then the Hypervisor discards the packet. | |||
* The Hypervisor reads the body of the packet beginning at the address 0x2400008C010. | |||
* The header and the body of the received packet can be read as many times as you want !!! They remain until next SYSCON packet is received | |||
which gives us the possibility to communicate with SYSCON on Linux easily :) | |||
